Description: sha 512
SHA-2 is a set of cryptographic hash functions designed by the NSA (U.S. National Security Agency).[3] SHA stands for Secure Hash Algorithm. Cryptographic hash functions are mathematical operations run on digital data by comparing the computed hash (the execution of the algorithm) to a known and expected hash value, a person can determine the data s integrity. For example, computing the hash of a downloaded file and comparing the result to a previously published hash result can show whether the download has been modified or tampered with.[4] A key aspect of cryptographic hash functions is their one-way nature: given only a computed hash value, it is generally impossible to derive the original data.
SHA-2 includes significant changes its predecessor, SHA-1. The SHA-2 family consists of six hash functions with digests (hash values) that are 224, 256, 384 or 512 bits: SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256.
